I don't really like this global state here.

The question is how to transfer the state from the new test suite to the tests.

I think this code should be moved to the file where the test suite is
implemented, so that the moment of initialization of these variables is more
clear.

+  switch (profile_type) {
+    case DEFAULT_THEME:
+      default_profile_dir_.Get() = path;
+      break;
+    case COMPLEX_THEME:
+      complex_profile_dir_.Get() = path;
+      break;
+    default:
+      NOTREACHED();
+  }
+}
+
+base::FilePath GetPathForProfileType(ProfileType profile_type) {
+  switch (profile_type) {
+    case DEFAULT_THEME:
+      return default_profile_dir_.Get();
+    case COMPLEX_THEME:
+      return complex_profile_dir_.Get();
+    default:
+      NOTREACHED();
+      return base::FilePath();
+  }
+}
